The new Mothwing Mountain Mimicry is extremely versatile, and is in the process of replacing my old favorite of Skyline Apparition. I, too, have tons of old camo and most of it is good in many applications. As I get older, I still look for bargains, but have also begun to realize the value in getting good quality hunting clothing to begin with. Cutting corners with raingear, first-layer to the skin stuff, etc., doesn't make much sense given the modern materials which wick away moisture, etc.
But is anybody like me and has a hard time getting rid of old camo clothing? I've even thought it would be fun to host a "throwback hunt" where everyone had to use camo at least 15-20 years old.
